A fossil fuel, as the name suggests, is a fuel made out of fossils by natural processes.They are known as non-renewable sources of energy. Although it may seem that fossil fuels were made very easily, unfortunately, it’s not so. To explain this concept, let us go back to some millions and millions of years ago.
These fuels were formed about hundreds of millions of years ago, during the Carboniferous period. During this period the Earth was covered with many swampy forests and wide and shallow seas. A large number of plants and planktons grew in these regions. After their perishing, they got buried deep under the ground, and at the bottom of the seas.
With anaerobic decomposition of these dead and buried organisms, they started decaying underground. Over the time sediments and rocks started piling on the top of them, creating intense pressure and heat under the ground. These factors eventually lead to the development fossil fuels from the ancient dead species.
Advantages of fossil fuels:-
Fossil fuels are very useful in our day to day life. Most of the activities like cooking, running vehicles, the industrial furnace is mainly dependant on fossil fuels.
- Abundant in nature: Fossil fuels have been an integral part of our life for many years now. This is just because these are readily available and in place. We just need to gather the essential resources and extract what is required. For example, coal, oil are in plenty, which just needs to extracted from beneath the earth and ocean floor. Highly advanced equipment are also available for this purpose.
- Easy to find: Since fossil fuels occur all over the world, deep under the ground, they are easily available. All we need to do is we need to find a source of the resource. Once found, it’s guaranteed that a lot of resources can be available from the same place. Some of the other fossil fuel, in any quantity, is available to every nation and country.
- Efficient in energy creation: Fossil fuels generate a huge amount of energy, with the usage of a small amount of that resource. A small quantity of petroleum, for instance, creates lots of energy, sufficient to run a car for a long distance.
- Generate jobs: Fossil fuels are responsible for the generation of thousands of jobs. Several factories need hundreds of workers for the mining, extraction, and refinement of fuels.
Disadvantages of fossil fuels:-
Fossils fuels have got no such major disadvantage except the two mentioned below:
- Harmful to the environment: This is a major issue which leads to further adversities to the environment. The burning of fossil fuels from vehicles, industries, and households releases some harmful gases to the environment and air pollution. These gases cause various serious problems to the health and environment.
- Abundant yet limited: This point is very crucial. Although they’re abundant in nature, they have a tendency to finish and can’t be replenished soon. It will take another hundred million years to form again. Hence they are known as non-renewable sources of energy.
Benefits of Solar Energy: Diverse Applications (Part 2)
With countless gadgets and technologies that can leverage solar power in the modern world, it is important to learn the benefits of solar energy and its diverse uses. My previous post about the diverse uses of solar energy offers an in-depth discussion of how this form of energy could be used at homes, holiday properties, and central power stations. Here are other applications of solar energy.
Solar water heating systems
In a home or business, hot water systems for kitchens, space heating, and bathrooms are nearly universal. What most people don’t know is that they can leverage solar power to get enough hot water in their homes and commercial buildings. Property owners can user thermal panels along with storage tanks to store the hot water. When needed, this water can circulate to a heater, shower or sink.
The modern ‘in floor’ heating systems and the traditional baseboard heating systems offer solar heat as the pre-heater to a traditional hot water tank or furnace. This will serve as the backup to your solar thermal system.
One of the common benefits of solar energy is the diverse industrial applications associated with it. For decades, solar energy has been the primary power supply of choice for many industrial applications, especially where power is needed in a remote area. In these applications, solar energy is cost-effective. This is because many individual uses need just a few kilowatts of electric power.
Solar energy is also used on transportation signalings such as lighthouses, offshore navigation buoys, road traffic warning signals, and aircraft warning lights. It is also used to power environmental or situation monitoring tools and even corrosion protection systems for well-heads, bridges, pipelines, and more. For huge electrical loads, it is cost-effective to configure the hybrid power system and link to a PV with a sizeable diesel generator.
The benefits of solar energy here include the reliability and minimal maintenance needed. That makes this form of energy ideal in regions that are hard to get to.
Lighting, water pumping, and heating in the developing world
In addition to off-grid properties, remote buildings such as clinics, schools, and community halls can benefit from solar power. It can power telephones, different pieces of refrigeration equipment, TV, and more. WHO (World Health Organization) requires every clinic to have these devices. Rather than having a base solar power generator for each dwelling, it is possible to configure a central power plant. The plant power homes through a local wired network. It can also serve as a battery charging station where the member of the entire community can charge their batteries here.
On a commercial building, atria can be effectively covered with PV modules. These modules are semi-transparent to offer shaded light. In factories, the large roof areas offer a perfect location for solar modules. Besides, the vertical walls of commercial buildings can offer opportunities for PV incorporation.
Whether it is charging a wireless speaker or powering a renewable, the list of uses and benefits of solar energy is endless.
Sources of Energy in Their Usage in Daily Life
Fossil fuels mainly consist of hydrogen and carbon bonds and are the important sources of energy since time immemorial. Man’s energy needs in every aspect are being served by fossil fuels only. These fuels are basically derived from the organic remains and decomposition of prehistoric animals and plants.
These organic remains are several million years old and are converted to carbon-containing fossil fuels by the extreme pressure and temperature of the Earth’s crust. These fuels produce a huge amount of heat and energy to meet man’s every need. Coal, petroleum and natural gas are considered to be the three most important fossil fuels. Let us discuss the four main types of fossil fuels known so far:
Petroleum, also known as crude oil or condensate is one of the most widely used fossil fuel. The word petroleum is derived from the Latin words petro and leum. Petro means rock and leum means oil. This fuel is highly valuable for mankind and almost every industry is dependent on this fuel. Hence it is also known as the “black gold”.
Petroleum is a liquid fuel that is made of hydrocarbons compounds inclusive of other liquid organic compounds. It is extensively used as fuel for automobiles, jets and to produce electricity. Its derivatives are also utilized in the plastic and medicine industries.
Petroleum products are derived from refined crude oil. Unprocessed crude oils that occur naturally are also referred to as petroleum products. Petroleum demand has been increasing year after year and which has immensely contributed to the water and air pollution worldwide. Because this is a stored reserve and due to high demand the oil field is depleting every year by around 2.5 per cent.
Coal is a flammable organic and one of the rich source of fossil fuel. It is usually brown or black in colour. About one-quarter of the total world’s energy and 40 per cent of the world’s electricity production is provided by coal. Several iron and steel industries in India and around the world are highly dependent upon coal.
Owing to its high use and demand coal reserves are also declining steeply and is on the verge of extinction within a few years from now. Hence we must find some alternative sources of energy that will serve the same purpose. Some of the alternative energy resources like solar energy, wind energy and hydro energy are being used widely, but the usage needs to be increased more.
Natural gas is a colourless gas and is a mixture of several hydrocarbon gases like methane, ethane, propane and butane. It is a combustible, convenient and efficient source of energy. Methane (CH4) is the main component of natural gas. It has two parts: conventional gas- which can easily be extracted and unconventional gas- which requires more advanced technologies for extraction.
Natural gas also helps in the generation of electricity and is widely used for industrial, commercial and residential purposes. Unlike any other fossil fuels, natural gas usually causes less pollution as this is comparatively cleaner. But like any other fossil fuel, this energy resource is also depleting rapidly.
Advantages of Solar Energy: Diverse Applications (Part 1)
There is a reason the advantages of solar energy have become a trending topic in discussions regarding renewables. Though it has been criticized for being less efficient and expensive, solar energy has proved to be beneficial. It is eco-friendly and financially affordable. Advancement in technology has made it easier to harness this form of energy.
Solar energy has an array of uses in both commercial and residential applications. Here are some of the most popular ways humans can use solar power.
Every household needs hot water and electric power. These basic needs are the top goals of solar thermal and solar PV systems. Over recent years, there has been an increase in the number of PV installations to buildings that connect to an electricity grid.
The demand for these systems has been stimulated partly by the government subsidy programs notably Germany and Japan. Also, the green pricing strategies of utilities or electric service providers have led to an increased demand for PV systems. The central driving force comes from the desire of companies or individuals to get their electric power from an eco-friendly, renewable source for which they pay low premiums.
In grid-connected systems, an effective PV system supplies electric power to the building, and all day-time excesses are exported to the power grid. These systems don’t require batteries as the grid can also offer additional power when necessary. But if you intend to be independent of the grid power supply, you need a battery to store power.
One of the most preferred energy solutions for holiday properties is Photovoltaic Systems. These systems have no access to the central electricity grid system. They are configured to meet power requirements less costly than extending the electricity grid to reach your holiday home.
Remote properties in sunny regions can get reliable electrical power for their radios, televisions, and lighting using a simple PV system. They also need a rechargeable battery to store all the power harnessed during the day, a charge controller, and wiring and switches. This system is often referred to as solar home systems (SHS).
The power storage capacity of the battery and the size of the PV module are designed to offer enough power and storage to meet the home’s energy requirements. This is commonly known as the ‘sizing’ system. Every system with battery storage must use the right battery design and specification for the system. That means a car battery shouldn’t be used!
Also, it is important to use high-quality fluorescent lamps as poor quality lumps will quickly blacken, dropping their light output. The charge regulator quality is also a critical factor in the overall reliability of the system. The PV modules can be mounted on the roof or a pole.
Central power stations
One of the advantages of solar energy is that central power stations can use it. In this case, applications use solar energy in a similar configuration to that a utility would utilize a power station. This is different from ‘distributed power’ applications or power distributed in low aggregate amounts.
To wrap up, the advantages of solar energy and its uses are unlimited.
